getMaximumIntegerDigits()方法是一个内置的方法，它返回一个实例的整数部分所允许的最大位数。

语法 :

public int getMaximumIntegerDigits()

参数:该功能不接受任何参数。

返回值:该函数返回整数部分允许的最大位数。

下面是上述功能的实现:

程序 1:

// Java program to implement
// the above function

import java.text.NumberFormat;
import java.util.Locale;
import java.util.Currency;

public class Main {
    public static void main(String[] args)
        throws Exception
    {

        // Get the Integer instance
        NumberFormat nF
            = NumberFormat.getIntegerInstance();

        // Stores the maximum
        int value
            = nF.getMaximumIntegerDigits();

        // Prints the maximum integer
        System.out.println("The maximum"
                           + " Integer digits: "
                           + value);
    }
}

输出:

The maximum Integer digits: 2147483647

程序二:

// Java program to implement
// the above function

import java.text.NumberFormat;
import java.util.Locale;
import java.util.Currency;

public class Main {
    public static void main(String[] args)
        throws Exception
    {

        // Get the Currency instance
        NumberFormat nF
            = NumberFormat
                  .getCurrencyInstance();

        // Stores the maximum
        int value
            = nF.getMaximumIntegerDigits();

        // Prints the minimum
        System.out.println("The maximum"
                           + " integer digits: "
                           + value);
    }
}

输出:

The maximum integer digits: 2147483647
